Description

[Detailed description of the invention] name of invention gravity lumbar traction device Background of the invention (Industrial application field) The present invention relates to a patient support device for providing gravitational traction on the lumbar region against a column. do.

(Conventional technology) The effectiveness of lumbar spinal reduction using gravity has been recognized. And this treatment method is 19 U.S. Pat. No. 4,205,865, dated July 3, 1980.

U.S. Pat. No. 4,2B9.179, May 26, 1981, and 1983 Charles Vu, inventor of U.S. Patent No. 4,422.452, dated December 27 Developed by Dr. Charles V. Burton It's here.

U.S. Pat. No. 4,269,179 discloses an inclined plate suspended from a metal frame. A vest is attached to a patient who is lying on a tilted table. It is shown. The slope of the inclined plate is for adjusting the traction force applied to the patient. A special plate and a support member for this plate are required for this purpose.

Additionally, the '179 patent teaches Flexible or non-rigid vest materials designed to provide reasonable adhesion are also shown. It is. This vest conforms to the contours of the patient's thorax to increase comfort. has been done.

The above-mentioned U.S. Pat. No. 4,422,452 is flexible and has cushioning properties, It relates to a traction vest with an insert that acts directly on the patient's torso.

U.S. Pat. No. 4.524.763, June 25, 1985, discloses Additions to said membrane type traction device for use with a vest wrapped around the torso of a person. improvements have been shown. The board is formed on a collapsible frame.

The most frequent drawback of the conventional devices is that the body always acts to counteract the force of gravity. This is a discomfort in the chest that turns into muscle contractions. For generally healthy patients Even considering the compression of the chest, the angle of the tilting table, that is, can withstand Traction power is limited.

Additionally, the cost of current vertical gravity lumbar traction systems is significant. Said Tilting tables add considerable cost and are cumbersome to handle.

(Summary of the invention) The present invention provides an outer shell of a reservoir that is attached to the patient's chest and supports the necessary amount of weight. A vest for providing vertical lumbar traction using gravity.

When the vest is suspended, the patient's elbows and forearms are placed on both sides of the vest. An arm rest with an elongated trough that supports part of the patient's weight is attached to the arm. Beth said The outer shell of the vest is heavy; Made to be able to transmit to the connection.

The outer shell is made of polypropylene that can be molded to roughly follow the contours of the patient's chest. Preferably, it is made of a lightweight semi-rigid material like Len. patient's body By following its contours, most parts of the vest are in contact with the patient's skin. The weight is distributed and pressure concentration is reduced, making treatment easier. Said The outer shell allows the patient's chest to expand forward without constricting the diaphragm. It can be made by leaving the part across the chest open.

The vest is supported on the door frame at a desired height, and is supported by the conventional crossbar. It is used in combination with a pull-up bar. The vest support connection section is located in front of the vest bottom section. with shoulders fixed to the front and rear sides or, in one version, to the armrest. There is. The straps are supported on the pull-up bar in the desired manner and, if necessary, the patient can Its length is such that you can place your toes on the floor and support some of your body weight. Can be adjusted.

between the patient and the door frame in order to correct the support angle to a better position on the pillar. A plate can be placed on the patient's back or front. the patient The slant board allows you to change the traction force by simply pressing your toes against the floor. There is no need to slope it.

Furthermore, by distributing the patient's weight with an arm rest or arm support member, This eliminates the need for the patient's entire weight to be supported by the vest. As a result, comfort or promotion treatment, making it easier for patients to tolerate treatment. At the same time, the patient The ability to vary the gravitational force allows for better relaxation of the torso muscles.

The ability to support weight with the feet allows complete interruption of traction forces, allowing for intermittent traction loads (desired intermittent repetition).

The traction device distributes your weight over a larger area of skin, so it It is now possible to add weight to the pelvis to increase traction, and the patient can It can withstand large forces.

The entire device is small, even including the crossbar or pull-up bar, so it is not suitable for home use. Make it easier.
